INSIDE a remote mountain in Texas, a gargantuan clock is being pieced together, capable of telling the time for the next 10,000 years. Once the clock is finished, people willing to make the difficult trek will be able to visit the vast chamber housing it, along with displays marking various anniversaries of its operation. On a website set up to track the progress of this “10,000-year clock”, Jeff Bezos, who has invested $42m of his own money in the project, describes this impressive feat of engineering as “an icon for long-term thinking”.
